ELUCID-DESI II. Revealing dark matter mass, tidal, and velocity (MTV) fields using galaxy group phase information
Qingyang Li, Xiaohu Yang, Wensheng Hong +24
We introduce a novel method for reconstructing the cosmic mass, tidal, and velocity (MTV) fields over the redshift range using the phase information of galaxy groups.…
Closing the Observational Gap in Cosmic Dynamics: AI-Enabled Reconstruction of the Universe's Vorticity and Rotational Flow Morphology
Ziyong Wu, Xu Xiao, Fuyu Dong +7
The cosmic vorticity field, an essential tracer of nonlinear structure formation, has remained observationally inaccessible because transverse galaxy motions are difficult to measu…
A possible detection of gas rotation in galaxy groups via the kinetic Sunyaev-Zeldovich effect
Tianyi Yang, Yan-Chuan Cai, Weiguang Cui +5
We utilise the kinetic Sunyaev-Zeldovich effect (kSZ) to measure the rotation of ionised gas within galaxy groups defined in the SDSS-DR7 galaxy sample, via their dipolar imprint o…
Mass dependence of halo baryon fractions from the kinetic Sunyaev-Zeldovich effect
Finn A. Roper, Yan-Chuan Cai, John A. Peacock
We detect the kinetic Sunyaev-Zeldovich imprint of peculiar motions of galaxy groups and clusters, using the photometric DESI Legacy Survey together with cosmic microwave backgroun…
Detection of cosmological dipoles aligned with transverse peculiar velocities
Yan-Chuan Cai, John A. Peacock, Anna de Graaff +1
Peculiar velocities encode rich cosmological information, but their transverse components are hard to measure. Here, we present the first observations of a novel effect of transver…
The Atacama Cosmology Telescope DR6 and DESI: Structure growth measurements from the cross-correlation of DESI Legacy Imaging galaxies and CMB lensing from ACT DR6 and Planck PR4
Frank J. Qu, Qianjun Hang, Gerrit Farren +51
We measure the growth of cosmic density fluctuations on large scales and across the redshift range through the cross-correlation of the ACT DR6 CMB lensing map and gala…
Probing the missing baryons with the Sunyaev-Zel'dovich effect from filaments
Anna de Graaff, Yan-Chuan Cai, Catherine Heymans +1
Observations of galaxies and galaxy clusters in the local universe can account for only of the total baryon content. Cosmological simulations predict that the `missing…
